Abstract
A fuel injection system for internal combustion engines, having a high-pressure accumulation chamber, which contains high-pressure fuel, and at least one fuel injection valve, which is connected to the high-pressure accumulation chamber. The fuel injection valve can inject the highly pressurized fuel through injection openings into a combustion chamber of the engine. The fuel injection valve has a control chamber, which is defined by a longitudinally mobile piston and is operationally connected to the fuel injection valve so that the injection cross section of the fuel injection valve is controlled as a function of the hydraulic pressure in the control chamber. A low-pressure accumulation chamber is provided, which can be connected to the control chamber, in which a predetermined fuel pressure is maintained in the low-pressure accumulation chamber that is lower than the pressure in the high-pressure accumulation chamber.
